Yes it does. This unit is not battery powered and must be plugged into a wall outlet to function.

No. It needs to be plugged in since there is no battery pack on the controller.

No, it plugs in. When I first saw it, I assumed it was battery-powered (and weak), or even manual. But it plugs into a standard outlet, and is plenty powerful.

It is designed to be plugged in. It has a cord not visible in the picture. (It is a great little personal lamp.)

It must be plugged in to charge up. After it is all charged up it does not have to be plugged in to work. And, works very well. Read directions before using though.

No, it comes with an AC adapter which need to be plugged in an available wall socket.

This was a gift for my son, and he said it works without being plugged in, with being plugged into an outlet, and it works being plugged into a computer. I hope this helps.

No Judith, it plugs in. That was not really a problem for me though. The power is.

No, it has to be plugged in for the lights to work. There is a small battery that keeps the clock and programming going if unplugged but it will not turn out without being plugged in.

Yes, it plugs in. I got it for my Dr I work for to have in his office and he loves it! Just make sure to turn it off once it's done to avoid overheating it.

Not necessary. It has an "Auto-off" feature, so you can leave it plugged in.

By default it needs to be plugged in. I think there are wireless dongles for it also.

The short answer is no, since it always needs to be plugged in to the power supply to work, but if you have a power outlet available to plug it in where you take it, then it should work.

It must be plugged in. It doesn't have a battery because it uses too much power for a battery.

No, it needs to be plugged in as it comes standard. I have no idea if you can buy some kind of adapter.

Yes it needs to be wired in or plugged in...but it works great when installed...
